Simultaneous extraction and separation of Cu(II), Zn(II), Fe(III) and Ni(II) by polystyrene microcapsules coated with Cyanex 272
(Elsevier B.V, 2009-02)
The preparation of polystyrene microcapsules coated with Cyanex 272 (MC-Xs) have been investigated and simultaneous extraction and separation behavior of Cu(II), Zn(II), Fe(III) and Ni(II) in both batch and packed column ...
Synthesis of sol-gel silica chemically bonded with cyanex 272 for the removal of Cu(II), Ni(II), and Zn(II)
(Springer Netherlands, 2009-05)
This article reported on the synthesis of SSCBB, a new solid-phase, sol-gel silica chemically bonded with [bis (2,4,4-trimethylpentyl) phosphinate], (BTMPP, anion of Cyanex 272) prepared with a sol-gel method, and its ...
Recycling waste tire into concrete-rubber composite
(Universiti Kebangsaan Malaysia (UKM), 2009-10-20)
This research is to recycle waste tire to a concrete-rubber. The objective of this research is to investigate the possibility of using rubber particles as a replacement for the natural aggregates in concrete. These ...
Selective leaching for the recovery of Copper from PCB
(Universiti Malaysia Perlis, 2009-12-01)
This paper reported on the leaching behavior of printed circuit board (PCB) using a new leaching agent of ammonia-ammonium persulfate, to recover copper. Cu and Zn leaching were found to be fast and reached equilibrium in ...
Extraction and separation of Cu(II), Ni(II) and Zn(II) by sol-gel silica immobilized with Cyanex 272
(Elsevier B.V., 2009-03)
The extraction and separation of Cu(II), Ni(II) and Zn(II) from aqueous sulfate-acetate solution were carried out using solid phase sol-gel silica containing immobilized Cyanex 272 {bis(2,4,4-trimethylpentyl)phosphinic ...
Reutilization of waste tire into concrete-rubber composite
(Universiti Tun Hussien Onn Malaysia (UTHM), 2009-12-14)
This research is to reutilize waste tire to a concrete-rubber. The objective of this research is to investigate the possibility of using rubber particles as a replacement for the natural aggregates in concrete. These ...
Characterization of BET, XRF and weight loss on dolomite and calcined dolomite heated at different heating time
(Universiti Sains Malaysia (USM), 2009-06-01)
Dolomite consist carbonate of calcium and magnesium (CaC03 and MgCO^). It is formed [CaMg (CO^J from chemical action of sea-water containing high magnesium on limestone. The purpose of this study is to characterize dolomite ...
Characterization of limestone and dolomite using x-ray fluorescent (XRF) for cement processing
(Mineral Research Centre, 2009-11-09)
Dolomite and limestone is considered under a sedimentary carbonated rocks. It contains almost same compound but major difference is on the amount of MgO and CaO which prove with XRF testing. MgO for dolomite shows 23% and ...
